Connection device for connecting table tops

ABSTRACT

A connection device for tables includes a shaft on which a first part and a second part are respectively mounted thereon. The two parts are pivotally connected with each other and have their own connection shafts. Each of the connection shafts is connected to a table top so that the two table tops are pivotable about the shaft as desired.

FIELD OF THE INVENTION

[0001] The present invention relates to a connection device thatincludes rings with different shafts in directions and each shaft isconnected to a table top so that these table tops can be positioned atdifferent positions.

BACKGROUND OF THE INVENTION

[0002] A conventional office table generally includes a table top withfour legs supported on a bottom of the table top. The top has a fixedarea and is located at a fixed level that cannot changed so that if theshort or a tall user may not be satisfied. Besides, there are manyoffice appliances are needed to put on the top for convenience ofaccess, so that only one table top will not large enough to allow somany appliances to be put thereon. U.S. Pat. No. 6,161,487 discloses anoffice table that includes different types of connection parts so as tolet the tops with different positions to meet different needs for theusers. However, in order to put the tops at desired levels, severalangled connection rods are used and which make the assembly job to becomplicated.

SUMMARY OF THE INVENTION

[0003] In accordance with one aspect of the present invention, there isprovided a connection device for tables and the device comprises a shafthaving an insertion on which a first part and a second part are mounted.The first part includes a first connection shaft and a second plate isconnected to an end of the first connection shaft. Two first rings areconnected to the first plate and mounted to the insertion. The secondpart includes a second connection shaft and a second plate connected toan end of the second connection shaft. A second ring is connected to thesecond plate and inserted between the two first rings. Two table topsare respectively connected to the first and the second connection shaft.

[0004] The primary object of the present invention is to provide aconnection device that is connected to at least two table tops so thatthese table tops can be swung about a shaft of the table or can bepositioned at desired positions.

[0005] The present invention will become more obvious from the followingdescription when taken in connection with the accompanying drawingswhich show, for purposes of illustration only, a preferred embodiment inaccordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0010] Referring to FIGS. 1 and 2, the connection device 10 for tablesof the present invention comprises a shaft 21 which has an insertion 22on a top end thereof and a base 20 on a lower end thereof so that theshaft 21 can be put on the surface by the base 20. A first part ismounted to the insertion 22 and includes a first connection shaft 113and a second plate 11 which is connected to an end of the firstconnection shaft 113. Two first rings 111 are connected to the firstplate 11 and mounted to the insertion 22.

[0011] A second part is mounted to the insertion 22 and includes asecond connection shaft 121 and a second plate 12 which is connected toan end of the second connection shaft 121. A second ring 122 isconnected to the second plate 12 and inserted between the two firstrings 111. The second ring 122 is also mounted to the insertion 22. Twowashers 50 are located between the first rings 111 and the second ring122, and the other two washers 50 are located on the two first rings111. A cover 30 is mounted on the insertion 22 and enclose theconnection device 10.

[0012] A first table top 40′ has an extension tube 42′ which receivesthe first connection shaft 113. A second table top 40 has an extensiontube 42 which receives the second connection shaft 121. Each of thefirst table top 40′ and the second table top 40 has a leg 41 which isconnected to a dual-wheel caster.

[0013] Referring to FIG. 4, the first part and the second part can alsobe connected with each other at an right angle. In other words, thesecond connection shaft 121 can be pivoted at a right angle relative tothe first connection shaft 113 so that the two respective table top canbe pivoted relative to each other to two different level positions.

[0014] While we have shown and described the embodiment in accordancewith the present invention, it should be clear to those skilled in theart that further embodiments may be made without departing from thescope of the present invention.
